• List of towns with Soil-Based Lot Sizing requirements as self-reported by municipalities responding to the annual OEP survey of municipal information.
• "Data Requirements for Site Review: Guidance for Planning Boards", (OSP May 1999) - This report presents a set of guidelines for State and local government in New Hampshire concerning the subdivision and use of land. The impetus for this report came from the release by the Soil Scientist Society of Northern New England (SSSNNE) of new Site Specific Soil Mapping Standards for New Hampshire and Vermont (SSSMS) in June, 1997.
• "Requirements for Soils and Wetlands Data in Subdivision and Site Plan Review Regulations", (OSP, DES September, 1999) - This document contains recommended language that can be included in subdivision or site plan review regulations to specify on-site data requirements for local reviews. It was designed to implement the findings of the Ad Hoc Committee on Site Review Requirements, an interagency, multi-disciplinary committee whose charge it has been to develop guidance for planning boards to use in reviewing local subdivision and site plans. The intent is to provide the planning board with guidance as to the type of data needed for making informed land use decisions about developments of different magnitudes and levels of intensity. For each level, the data recommended to be required is specified in this document, as well as the standards to be used in preparing the data and the type of professionals qualified to do the work.
• "Site Specific Soil Mapping Standards for Use In Subdivision and Site Plan Review Regulations", (OSP November 1997) - This memorandum provides background on the development of the new soil mapping standards developed by the Society of Soil Scientists of Northern New England and presents model language that can be incorporated into local subdivision and site plan review regulations to update existing soil mapping standards.
